I really like the new powerpro battery..

Silver as a material? Has that been confirmed? Would make for a great boon for silver hoarders like me! The price would definitely get jacked up.

The life power batteries I dig on only because I've worked on them before. On the other hand the newer smaller eg4 setup look compact, slick, and spacious so that a tough 1I didn't realize it until last night, but I think this battery is pretty sweet. The look, form factor, busbar with quick connectors, communication ability, internal heaters, outdoor rated and the list goes on.
Now I want to dump my server rack batteries. Which one would you rather have. This setup:

I just love the look. I love sci-fi movies and I want to make a system that looks really cool. I'm thinking four batteries and an 18K would do everything I need.
The communication set up was a bit difficult. I should probably make a setup video for beginners. I think anybody could figure it out though if they read the whole manual. I think there should be a tutorial on designating the master battery right after the communication protocol set up.
But besides that, this battery is pretty impressive. I'm going to be asking all of the other companies why they don't have this type of battery. Hopefully we can get some healthy competition into the market.
What do you guys think. Is there anything that you dislike about this battery that I'm missing? I really didn't think I was going to like it but seeing it in my shop in person, makes me want only these batteries now. I think I might move my server rack batteries into my garage today. I only have two power pro batteries but I could run everything I need with them. I'm almost at 5 megawatt hours with my 18K, so I really don't need to push tons of loads through it anymore. Making a beautiful system would be fun. I want to add LED lights behind it and make it pop
I dig the lifepower4 setup only because I've seen what they can do 1st hand. But the smaller unit looks pretty slick so you can't go wrong with either selection.. My question is, are four of those in 1 area less of a foot print than a single battery rack??I didn't realize it until last night, but I think this battery is pretty sweet. The look, form factor, busbar with quick connectors, communication ability, internal heaters, outdoor rated and the list goes on.

Not in footprint or wall space taken.
They just don't stick out as far from the wall.

This is the first prefab battery that has gotten my attention. I have always built my own 280AH packs, but the water proof- heated option and capacity got my attention. Never cared for 100AH server rack. They didnt offer anything I couldn't easily do myself and save money.
Would you recommend his book(s)?
the one you linked, (and he also has one on grounding/bonding) looks good. Pricey, but I’ve watched a lot of his videos, and I find,him easy to understand.

In the electrical field, Mike Holt is a superstar.

i bought his book and it has proved very useful for me, as I am just a Homeowner/DIY type
The military uses tons of silver in batteries for missiles and other items. It takes allot of power to run IR/trancievers etc...
I'm pretty sure its not new tech for Toyota but they are refining it for production, low materials, etc...???
https://ts2.space/en/toyotas-solid-...Development,life, and enhanced overall safety.
......Toyota’s researchers proposed utilizing a silver-carbon (Ag-C) composite layer as the anode, which allowed the battery to support a larger capacity, a longer cycle life, and enhanced overall safety. The ultrathin Ag-C nanocomposite layer is just 5µm (micrometers) thick, which allowed the team to reduce anode thickness and increase energy density up to 900Wh/L. Toyota has committed to commercializing its new solid-state batteries, with ambitions to have cars run using the new technology on the roads as early as 2027........
The layer is pretty thin but it adds up quick. Not sure where they plan on getting all the silver from. At current rate, solar is going to suck up most of the worlds silver by 2030.
Which book(s) did you buy?

As much as they try to keep the videos locked up Mike Holt has a lot of good stuff on youtube. I love listening for the fact that he will call out silly rules and practices where he sees them, like additional grounding rods at the solar array.
The limits on the size and location of batteries energy storage systems as well as the requirement for UL 9540 listing, are not in the NEC. Those requirements are in the IRC(International Residential Code) section R328, and the International Fire Code for buildings not under the IRC.
Google on “Amphenol battery connector” to see manufacturer and distributors.
Okay.. must be one of these? https://www.digikey.com/en/products...ZX4AnAJYA7AOYgAvvMIsyIgK5iAMkQDWAAgAKmNdm7ygA

Try Solar, the Grid will always take you back
lithium weight has no hacks, 3x server packs are 315lbs. You may have an Alibabba cell special...
I was thinking that I read that the Lifepower4's were about 104# each? I just can't seem to find it.

280-310ah cells weigh about 12 lbs, so 192 lbs are just cells. That means the EG4 Power Pro has over 100lbs for the bms, wiring, and case etc

Man this post blew up, these batteries don't make much sense from my very budget conscious perspective. I'll keep on with the eg4 batteries as it's the only option my family can afford ATM

Yikes how much are they spending on 80+ lbs of case? Is that the reason for the premium cost or is it R&D?

I really don’t understand what the fixation is for some on the weight of the unit minus the cells.
It’s designed to be all weather and to hold the weight and items within it safely. Outside if need be, and it has internal heaters.
So do all that, have some UL cert, make it look nice, and see what you come up with.
